To 'all 'whom it may concern:

Be 1t known that we, JOHN J AcoBsoN and JOHN Toonen, both citizens ofthe United States, and ,residents of New York, county of New York.. andState of lNew York, have mvented an Improvement in Machines for` fTransferring Designs, of which the following'-` that, by a description,in. connection with the accom-l anylng drawings, 1s a specification,like etters on the drawings representing like parts'. v

'I he present invention relates toa machineor apparatus for transferringa design from a plane surface to a cylindrical surface, or vice versa,in cases where it is essential that the design transferred from onesurface shouldexactly'cover the other surface. 'I he machine isespecially intended .for use. in.

transferring from a hat printing surface an acid .resist to the'su'rfaceof a roller, so that the roller Acan be subsequently etched and therebyhave a printing surface formed upon it for continuous, web rintlng. Itis, of

course, necessary, in t ls case, that the design ltransferred to therollenshould ferred, in nearly every case, will either mis-l match' atthe ends, or be separated a slight distance so that the printi surfaceformed onfthe roller, if etched, wi be incorrect or incomplete. In'accordance with the invention, these "diiiiculties are overcome ,byproviding the roller with a controlling device 'which is ca able ofvarying the peripheral velocity of t e roller, increasing or retardingthe same, the ydevice being adjustable, yso l process of trial, suchadjustment can, be ma actly fit the surface of the roller. example, itis found, on rollin the roller over Atheprinting surface, that t e lendsof the design do not properly combine, fthe machine can adjusted so asslightly to retard the eripheral' velocity of the roller until. it4 iis.

ound that the meeting point of the .edges of the design cannot bedetected, the slightA fore'shortening or condensation of the designbeing even throughout, so as knot to be e as' to cause thedesign to ex-vIf, for

'y noticeable. lf, on the contrary, the edges of the design fail tomeet, the peri heral velocity of the roller can be slight yzincreasedbeyond the normal to attain the desiredresult.

' In carrying out 'the invention, the .roller is mounted in a travelingframe, and provided lwith a-gear which is arranged to mesh with a rackso that by a -movement of said 'rack relative to the movement of theroller, the peripheral velocity of said roller can be .in-

, creased or diminished with relation toi ts norwheel of a differentcircumference from that of the roller so that a certain amount of travelof the rack is required inorder to cause vthe roller to rol] at itsnormal peripheral velocity, -so that by varying the amount of suchtravel, the velocitv of the rollerl can be va-4 "85 .ried either way. 1nthe construction shown,

the roller .is mounted in 'a traveling carriage, and the rack isconnected therewith by means of a lever, so that by varying the positionof the fulcrum of said'lever, the relative amount of travel of the rackmay be varied. By providing the lever with an adjustable screw,therefore a very delicate adjustment can be obtained without difficulty,and aneXact .transfer of the design accomplished.

Figure 1 is a perspective view of an appa'-, ratus embodying theinvention; Fig. 2 is a longitudinal section; and Fig. 3 is an endelevation. i

'As herein shown, the roller u is provided with journals a2 which run injournal boxes or bearings b2 in a traveling frame l which arranged to bepushed along over aframe or support B upon tracks B2 formed along the51'05- Sl.

es of said support.. This table or 'support is further arranged to holda printing 'plate e, or al late upon whicha de'signfis to be printed, te plate c being herein shown as a printing surface from which a designis to be trans- '116 some composition which is more or less yieldvwhenin its normal position, is supporte ing, so as to transfer the pigmentor resist evenly to the surface of the metal roller. As herein shown,thc printing plate c is held in position by means of clamping members c2and is vertically adjustable with relation to a supplemental table C onthe support B by means of adjusting screws c3. The roller a above theprinting surface c, the journals of the rollerbeing shown as resting onsupplemental track members B3 which are longitudinally adjustable withrelation to the track members B2,so that, as theframe l) is pushedtoward the printing surface c, the roller o'l maybe gradually let downinto contact with said printing surface at exactly the proper time. Byproperly adjusting these 'track members, the roller may be brought intocontact with the plate at a point where the units of the design areexactly comple- Inentary to the units of the design where the roller islifted. In this case, it is unnecessary to have the plate cut to alength equal to the periphery of theroller.

In order to true the late, c'. e., to bring it to an exact right ang eto the axisof the roller, the'su vplemental table C upon which it ismounte is capable of rotation with relation to the support B, beingshown as provided with a spindle O2 extending through the support B andprovided with a screw clamp C3 to hold it firmly in position afteradjustment. In order to obtain a delicate adjustment, the table C isshown as provided with a threaded lug to receive an adjusting screw C4,which is held longitudinally stationary in a lug B4 secured to a part ofthe support B, by means of flanges C5. The table @is further shown asprovided with an indicator linger C, which travels over a scale B* -onthe frame B. In order to vary the periph` eral velocity of the rollerofthe said roller is provided with a gear wheel c3 herein shown asslightly smaller in diameter than the diameter of the roller itself, thesaid gear wheel meshing with the teeth of a rack d which is arranged totravel with the frame b,but'at a different velocity. It will be seen,therefore, that if the velocity of travel of the rack d is properlyproportioned to the diiference ibetween the diameter of the gear a? andthat of the roller a, the roller will travel normally, that is to say7at exactly the peripheral velocity at which it would travel if it weremerely rolled over the surface c without being otherwise influenced.If,.however, the

velocity of the rack is increased the peripheral velocity of theroller'will be retarded,

and vice versa.

b by means of a lever e, having a stationary pivotal support e2, therack and the carriage being respectively connected with said leverbymeans of swivel joints d2 and l. In, the construction shown in which thegear a,3 is smaller than the roller a, the normal v travel of the earmust be less than that of the roller, an the swivel connection d2 is,therefore, placed between the connection b3 and `thefulcrum e2, so thatthe movement of the carriage bis Amultiplied with relation to themovement-of"therack d.' I In order to .vary the movement of the rack dwith relation to that of the carriage b, and thereby to vary theperipheral velocityzof the roller a, the fulcrum e2 of the lever c isadjustable, the said fulcrum e2 being herein shown as formed on asliding member e3 mounted on of the short lever arm, the reverseoperation being performed when the relative Inovernent of the rack is tobe decreased.

In the operation of the' machine, the carriageb is pushed forward, andas soon as'the j Y- said carriage reachesthe ends of the su pleinentaltracks B3, the surface of the ro er a gradually comes down into contactwith the surface of the printing plate c, the roller then rolling overthe said printing surface at its normal, its increased or its decreasedperipheral velocit according -to the adjustment of the rack ever, e,thus rolling normally, or with a slight backward or forward slip,.sothat as it reaches the end of thev design, and rides up thecorresponding tracks B3, at the other end, it will have the designexactly transferred to its surface.

It is desirable to restore the carriage and roller, at the end of theoperation, in order to readily remove the plate, if the design has beencorrectly transferred, or to adjust the carriage and wash the rollerifthe design has been incorrectly transferred. In order that the carriagemay be thus restored without having the roller come in contact with thesurface of the plate, the saidparriage is provided with meansuwhereby itmay be raised above the tracks B2 and supported independently thereofduring the return move- .frame b which rests on the trac i Bz'when in asubstantially vertical position. The said l arms b4 and b5 are connectedby links b and reaches the vertical position, the arm b b7 with the endsof a lever 68, also pivotally connected with the frame b, the arm b5having a spring b9 which tends to hold it and the arm b4 in such aposition as to main tain the said arms in-a vertical position with thecarriagev raised.v In the forward movement of tne carriage b, the arm b4is brought relative to the plane surface with which it is in contact,substantially as described.

' 2. In. an apparatus for transferring a deinto contact with anadjustable stop B2 so sign from a plane surface to a-cylindrical that,as the carriage is pushed forward, the surface, or the reverse, thecombination with lower end `of said arm is forced back until it thecylindrical surface, of a traveling frame being acted links-b and thesaid armsthus coming into contact with the supplemental tracks B7, vandlifting the carriage b high enough to prevent the roller a from cominginto. contact with the plate c as the carriage is moved back. Thus, inthe normal position at the beginning of the operation, the carriage b issupported above tne main tracks B2, but must be lowered during theforward niovement first into contact with the tal tracks B7 from whichit is dropped to the surface of the plate. This is accomplished by meansof a tripping device B9, best shown, in Fig. 2, as a trigger having astop B1 which holds it in tne position shown, the said trigger being inthe path of the lower end of the lever bs, so that, in the forwardmovement of the carriage, the said lever bs is rocked against the stressof the spring b9, thus throwing thel arms b4 and b5 out of theirvertical position, and permitting the frame b to drop. The trigger Bs isshown as pivotally supported and provided with a spring B12, and has aninclined surface on tne side first reached in the return move-V ment ofthe carriage, so that it will not act upon the lever 68 during suchreturn move-l ment. At the end of the forward movement, the carriagewill be lifted through the action of the supporting arms b4 and b5, and,in the return movement, will be supported by said arms on thesupplemental tracks B7 so as to be out of Contact with the surface ofthe plate.

It is not intended to limit the invention to the specific constructionand arrangement l herein shown and described, since modications maybe-made without departing from the invention.

also 1 for said cylindrical surface; a gear rotatably ubpon lthrough thelever bs and connected with said cylindrical surface; a movable rackmeshing with said gear; and means for varying the movement of said rackwith relation to that of said traveling frame, substantially asdescribed.

3. The combination with a frame or support, a roller, and a' travelingframe vprovided with journals, therefor; of a gear connected with saidroller to rotate therewith; a rack meshing with said gear; a leverhaving an adjustable, pivotal support or fulcrum; and

means for connecting said carriage and said' rack with said lever atdifferent points, substantially as described.

4. 'The combination with a frame or support; of a supplementalplate-holding table rotatable on a vertical axis with relation to saidframe; an adjusting device for moving said table on its axis; and aroller-supporting frame movablev along said frame, as set forth.

5. The Vcombination with a support; of main and supplemental tracksformed on said sup ort a roller-carrying frame adapted to trave on saidmain tracks; a supporting member pivotally connected with saidrollercarrying frame; and means for moving said member on its pivot intoengagement with said supplemental tracks to raise and support theroller-carrying frame out of engagement with said main tracks as setforth.
